OK, after reading about this page for 15-20 minutes, it looks like this software can read modbus directly. Ideally you don't even need my converter at all. You can plug...

I don't think it is possible. I have seen modbus client implementation for the ESP, but a modbus master. The only option I can think about is a modbus RS485...

Well, I found the modbus documentation for my inverter on the internet. From the above screenshots I can't tell what type of inverter you have, and I have no idea...

Well, it is not clear for me either. But I think you need to try with some of the high registers and see they provide and useful information. Like Input...

Hi Helge, Thanks a lot for your work. I know I should really switch from the Arduino IDE to VSC. Everyone says that it is so much better. But I...

As long as Growatt and the smart meter use the same communication speed and settings (9600, 8, 1, N) and the two devices are set to different slave ID, it...

Possible, but I have no way of telling how the inverter works internally. But both sketches write to the modbus register, therefore I don't see how the SetMaxOutput in our...

I think the smart meter connection is used to connect a meter so the inverter can limit the production to match your consumption (not to sell electricity to the grid)....

I have a 6 year old 3000-TL, and I also have a MIN 3000 TL-XE and MIC 1500 TL-X. The MIN and MIC models have the same connector (as documented...

Hi Matthijs, Oh, these are great changes. I am still using my much older version of the code before it got re-worked by Joe. Wifimanager is great, actually I should...
